Lily Allen unveils new single 'Air Balloon' - listen

'Air Balloon' serves as the singer's latest release. Listen to the track in full below:

"If you thought the Bear and Hare was annoying, you won't want to watch this," she tweeted of the song, referring to her recent cover of Keane's 'Somewhere Only We Know' for the John Lewis Christmas advert.

'Air Balloon' - out on March 2 - was co-written by Allen and Shellback, whose previous credits include One Direction's 'Kiss You', Maroon 5's 'Payphone' and Taylor Swift's 'I Knew You Were Trouble'.

The song marks the second single after last year's 'Hard Out Here' from her third studio album, which is due for release later this year.
